What is the most common error made while using an AED?

Applying the pads improperly is indeed a common error made when using an automated external defibrillator (AED). For the AED to effectively deliver a shock to a patient in cardiac arrest, the pads must be placed correctly on the chest. The placement of the pads is crucial because it creates a pathway for the electrical shock to flow through the heart. Misplacement can lead to ineffective defibrillation, exposing the patient to additional risks and potentially worsening the situation.

Proper placement typically involves putting one pad on the upper right chest and the other on the lower left side of the chest. If pads are placed incorrectly, there may be an insufficient connection, or the electrical current may not reach the heart effectively.

Although other factors like failing to turn the device on or not assessing the patient before use can be significant, they occur less frequently than issues related to improper pad application. Ensuring that the pads are correctly positioned is fundamental to the success of using the AED and restoring a normal heart rhythm.
